To all whom it may concern:

Be it known that l, ALEXANDER SPENCER, a subject of the King olI Great Britain and ireland, residing in the city of London, England, have invented Improvements in Bogies 'l'or Railway and the Like Vehicles, ol which the vfollowing is a specif cation.

This invention has reference to bogies 'l'or railway and the like vehicles and has for object to provide an improved construction oi such bogies wherein greater smoothness in running is obtained than with such bogies as heretofore usually constructed.

For this purpose the bolster which directly supports the vehicle, instead of being suspended Yfrom the bogie frame, is suspended 'from a supplementary bolster or holst-ers. Both the main and the supplementary bolsters may be supported on spring planks, that ol' the main bolster being suspended, as by links, from the supplementary bolster or holsters and that or those of the supplementary bolster or bolsters being suspended, as by links, from the bogie irame.

Figure l of the accompanying drawings shows in part central longitudinal section one construction ol` bogie embodying this invention, suitable l'or a railway vehicle, Fig. 2 shows a portion oi' such bogie in plan. Figs. 3 and 4 are transverse sections corresponding to the lines A A and B B respectively oi' Fig. 2.

a is one of the longitudinal side members of the bogie l'rame, l) is the main bolster adapted to support the vehicle through a central swive plate, not shown, and bearing blocks c, as heretofore usual. The bolster?) is supported, through springs indicated diagrammatically at d, upon a spring plank e that is carried by links f through bars g connected to the plank e by bolts h; j, y' being wooden blocks interposed between the bars g and spring plank e. The bars g are formed with trunnion like ends 7c each mounted in the lower end of a link f. At their upper ends the pair of links f at each side are mounted to turn on pins m which are carried by Yan intermediate bolster n. rihe two intermediate holsters e, which are connected at their ends by plates o, are each supported by a spring plank through springs indicated diagram matica ly at q. The two spring planks p rest on longitudinal bars r that are prevented from lateral movement relatively to the spring planks by brackets s, and whose ends, which are turned to `form trunnions, l

are supported in the lower ends ol' links t that at their upper ends are pivoted to pins u carried by the transverse members o ol' the bogie iranie. T he inner ends el' the pins m are each supported in a bracket w arranged to iorm a rubbing block that works against a corresponding rubbing block a; fixed to the main bolster l). The pins u el' the links t are each supported at one end by the corresponding cross member o and atits other end by bracket t1 which is secured to such cross inember o.

e indicate rubbing blocks fixed to the bolsters n and working against the rubbing blocks y.

ln the example illustrated, the lower ends oi each pair of spring plank carrying links f and t are farther apart than their upper ends but in some cases the links can be vertical or inclined outwardly toward their upper ends instead of toward their lower ends, or the links supporting the main bolster may incline one way, while the links supporting the intermediate or double bolster are inclined the other way.

Stops or buffers, for example of rubber, may, if desired, be arranged between the ends oi the bolster l) and the connecting members 0 of the compound bolster, or between the bolster members 0 and the bogie frame niembers a, or such stops or bellers may be arranged in both these positions.

For the purpose of enabling the bogie to support with suitable resilience a vehicle when lightly loaded as well as when heavily loaded, the springs d, supporting the main bolster t may be comparatively light springs suitable for a light load, stops being provided to limit the downward movement of such main bolster and thereby prevent these springs being unduly stressed, the arrangement being such that the springs g oi the supplementary bolster come into more effective action when the vehicle is heavily loaded at which time the springs d may be inoperative by reason or' the stops.

rlhe details of construction may be other than in the example shown, without departure from this invention.

W'hat l claim is l. ln a bogie for railway and the like vehicles, a bogie frame, a bolster supported by said frame and capable oi movement relatively thereto in a transverse direction, and another bolsterl suspended from said framesupported bolster.
